Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevating and lowering device capable of continuously transferring materials and the like from a vertical direction to a lateral direction without transferring them to another carrier by a carrier in the carrier. Concerning a carrier device.

[0002]

2. Description of the Related Art Conventionally, for example, when carrying materials and equipment from above ground into a tunnel that is excavated underground, the desired article is first carried by a lifting facility installed in a vertical shaft connected to the tunnel, and then It is transported to the target position by truck etc. along the track laid in the tunnel. For this reason, the materials and the like that are unloaded by the lifting equipment for carrying in from the above-mentioned ground part are reloaded from the carrier of the lifting equipment to the loading platform of the truck. Therefore, a lifting device such as a gate crane for transfer is installed at a lower position of the lifting equipment.

[0003]

As described above, at the position where the conventional lifting and lowering equipment intersects with the equipment for transverse transportation, it is necessary to reload the objects to be transported. Heavy equipment must be provided. However, in the case of underground excavation work, the loading of materials and the like into the tunnel and the loading and unloading of excavated earth and sand are carried out in parallel. Many workers are required unless a system with good workability is adopted.

However, in the conventional equipment for loading and unloading materials and the like, a lot of labor is required because the objects to be transported must be reloaded and transported at the contact points of the elevating part and the traverse part.
Moreover, since the workability due to transshipment is not good, the efficiency is low and the construction cost is high. Further, it requires a long working time in a bad working environment, which is not preferable in terms of occupational safety and health.

In the present invention, for the purpose of solving such a problem, for example, the number of persons who need to carry in and out materials and the like from the above-ground part to the inside of the tunnel is the minimum, and the destination can be reached without any trouble such as transshipment. It is an object of the present invention to provide an elevating / conveying device that can continuously ascend / descend and traverse.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention comprises a rack mounted on one side of a support tower extending in the vertical direction and a rack attached to one side of the support tower. It consists of a lifting device and a traversing carrier that allows the traveling carriage to traverse on a rail laid on a plane from the lower part of the lifting device to the required position. The lifting device can be attached to and detached from the lowest required length of the support tower. The traveling carriage of the traverse transport means is mounted with both the carrier of the lifting device and the lowest cut-off portion of the support tower in a state where the carrier of the lifting device reaches the lowest position, and the lowest position of the lifting device. It is configured to be self-propelled between the transport target position and the transport target position.

Further, according to the present invention, when a plurality of the elevating devices and the traverse conveying means are arranged in series to form a conveying path in multiple stages, the traverse conveying means is an upper part of the second and subsequent hoistways. The platform is installed on the platform to allow the traveling carriage to move to the hoistway, and this traveling carriage has a connecting mechanism for connecting and disconnecting the segment of the mounting support tower to the top of the supporting tower arranged in the hoistway, The transporter can be configured to move to the hoistway along the connected support tower.

[0008]

According to the present invention having such a structure, the objects to be transferred loaded in the carrier are re-transferred from the loading / unloading position of the objects to be transferred to the target position by the traversing means on the plane through the elevating device in the vertical direction. The transfer section can be directly operated without any operation, and the transfer section can be operated unattended by operating in cooperation with the operation of each part.

Further, in the case where the transport paths are serially connected in multiple stages, the traversing transport means sequentially connects the support tower segments of the lifting device to the existing support tower on the moving side of the transport device, so that the transport object mounted on the transport device is transported. It is possible to automatically operate to a target position via a multi-staged conveyance path without transferring.

It is preferable to be able to reconnect with.

After the carriage 22 has been traversed to the target position in the tunnel B, the carriage 22 is stopped at that position and the objects loaded on the carrier of the carrier 15 are conveyed at that position. It is unloaded by the provided lifting device, and the carriage 15 and the support tower segment 11A are left as they are for the next work, and the traveling carriage 22 is caused to travel backward to the lower part of the vertical shaft A.

In order to return the carrier 15 from the traverse operation means 20 to the lifting device 10, the support tower segment 11A is connected to the lower end of the support tower 11 by the connecting mechanism 24 by operating in the reverse order of the operation procedure described above, and then the power supply is supplied. Returns the energization state to the lifting drive of the carrying device 15, raises the carrying device 15 as the lifting device 10 along the support tower 11 to the transferred object delivery position C on the ground,
The next transported item is loaded. After that, by the above-mentioned operation, it is possible to send the object to be conveyed from the above-ground portion into the underground tunnel without performing the transfer operation. Of course, the reverse operation can be carried out in the same way from the inside of the tunnel to the ground.

Next, another embodiment of the present invention will be described with reference to an elevating / conveying device for conveying an object to be conveyed to a target position having a large height difference, the conveying paths being provided in multiple stages.

And rack 13 is adjusted). In connection with this operation, the terminal is connected so that power is supplied from the power supply to the lift drive device of the carrier 15. For connection of this terminal, for example, support tower segment 11A
Is preferably performed at the same time as is connected to the top of the existing support tower 11.

Support Tower 11 of Support Tower Segment 11A
When the connection to the second lifting device 10A is completed, the lifting drive 17 of the carrier 15 is operated to move the carrier 15 to the support tower 11 of the second lifting device 10A.
Down to the bottom of. At the lowest position of the support tower 11, the second traverse operation means is used as in the case of the above embodiment.
Lower support tower segment on 20 'trolley 22
When 11A is lowered from the lower part of the support tower 11 by the operation of the connecting mechanism 24 attached to the traveling vehicle 22 to disconnect the connection, the state becomes traversable. Therefore, the traveling carriage 22 can be conveyed on the rail 21 by traveling along the rail 21 to the target position in the tunnel B '.

In order to return the carrier 15 to the above-ground portion, reverse operation can be performed by operating each portion in reverse of the above operation. Therefore, if a sensor or limit switch is arranged and controlled so that the operation at the conversion position in each movement direction can be remotely controlled by using one carrying device 15, automatic operation becomes possible. In addition, for example, if it is possible to provide a double-track cross-path shelter on the traveling path of the traveling vehicle at the tunnel part, it is possible to carry using a plurality of carriers. Further, the lifting / lowering transporting device of the present invention can be adopted when transporting an article into a multi-story building constructed on the ground, if necessary.
